IMPROVEMENT lN DEVICES FOR OILING THREAD IN SEWING-MACHINES.

Specification forming partof Letters Patent No. 40,484, dated November3, 1863.

To all whom it may concern:

Be it known that I, O. R. HYDE, of East Olevelamhin lhecountyot'Cuyahoga and State of Ohio, have invented a new and ImprovedDevice for ()iling or Greasing the Thread in Sewing-Machines,and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is aside view of the needle-arm of a sewingmaohine with my device attached.Fig. 2 is a top view of the same. Fig. 3 is a transverse verticalsection of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is the box, represented of cylindrical form, and arranged in ahorizontal position on one side of the needle-arm B. The opening a forthe reception of the sponge 0 is at the end next the needle-arm, and islarge enough to allow the sponge to be crowded through it, but not largeenough to permit it to slip out easily when the box is detached fromthe'needle-arm. The sponge is large'enough to till the box compactly.The oil-hole b is in the top of the box, and is just large enough topermit a drop of oil -or other lubricating material to be introducedfrom the spout or feeder of an oil-can, the quantity required being verysmall, as the thread is not to be saturated, but merelylubricatedslightly on the surface. The slot 0 for the in-' ttoduction of thethread is also made in the top of the box, and isjust wide enough forthe passage of the thread through it without friction against its sides,and it may extend rather more than onethird or nearly half around thebox.

The box may be made of light sheet metal, with soldered-joints, and thepiece which forms the end next the needle-arm, and in which the openinga is formed, is made long enough to form the two lips d d of the clasp,by which to attach it to the needle-arm, the said lips being formed tofit snugly to the larger back portion of the needle-bar, and the opening0 between their extremities being wide enough to permit the clasp topass over the smaller front portion of the needle-arm by holding thesaid openingin adownward position. When placed on the smaller part ofthe arm the clasp is turned round far enough in the proper direction tobring the box on the proper side of the arm, and then pushed back alongthe arm to a point'where it fits tightly and where it will hold the boxsecurely. When the box has been so applied to the arm it will beunderstood that the hole a is closed by the arm, so that it isimpossible for the sponge to get out. The position of the box upon thearm should be such that when it is not desired to lubricate the threadthe latter may pass under the box without touching or bearing hardagainst it, as shown by the dotted red line in Fig. 1.

When it is desirable, owing to the nature of the work or material to beoperated upon, to lubricate the thread, it is, without unthreading theneedle, simply passed over the box and into the slot 0, and by itstension it indents itself into the sponge, and as it is drawn from thespool toward the needle in working it is lubricated.

Other materials, as wool, might be substituted for the sponge in the boxA as a means of containing the oil or lubricating material.

I do not claim broadly the passing of the sewing-machine thread throughor over an oilcontaining vessel or substance; but,

Having thus described myinvention, what I claim as new. and desire tosecure by Letters Patent as an improved article of manufacture,

A sewing-machine oil-sponge box, made, as herein shown and described,with an opening, a, to receive the sponge, and clamps d d, to bind thebox against the needle-arm and close the said opening, all as set forth;

0. R. HYDE.
